Christopher Shanahan SC has been appointed as an Acting Commissioner of the Corruption and Crime Commission (CCC).
Attorney General Michael Mischin said Mr Shanahan was a very experienced and senior barrister with considerable knowledge of the commission and its operations.
Mr Shanahan, who will join the other current Acting CCC Commissioner Neil Douglas, will continue in his practice at Francis Burt Chambers in conjunction with his new part-time role at the commission.
He previously served as an Acting Commissioner under former commissioners Hammond and Roberts-Smith in two consecutive terms between 2005-07 and 2007-10.
The Attorney General paid tribute to the contribution of outgoing CCC Commissioner Roger Macknay, who will retire today.
Mr Macknay, who was appointed as Commissioner in 2011, signalled his desire to step down from the role in November last year to spend more time with his family.
